A suicide attack is any violent attack in which the attacker accepts their own death as a direct result of the method used to harm, damage or destroy the target. Suicide attacks have occurred throughout history, often as part of a military campaign such as the Japanese kamikaze pilots of World War II, and more recently as part of terrorist campaigns, such as the September 11 attacks.

While there were few, if any, successful suicide attacks anywhere in the world from the end of World War II until 1980,[1] between 1981 and September 2015, a total of 4,814 suicide attacks occurred in over 40 countries,[2] killing over 45,000 people. During this time the global rate of such attacks grew from an average of three a year in the 1980s, to about one a month in the 1990s, to almost one a week from 2001 to 2003,[3] to approximately one a day from 2003 to 2015.[2]

Suicide attacks tend to be more deadly and destructive than other terror attacks[4] because they give their perpetrators the ability to conceal weapons, make last-minute adjustments, and because they dispense with the need for remote or delayed detonation, escape plans or rescue teams.[4] They constituted only 4% of all terrorist attacks around the world over one period (between 1981 and 2006), but caused 32% of all terrorism-related deaths (14,599).[citation needed] Ninety percent of those attacks occurred in Afghanistan, Iraq, Israel, the Palestinian territories, Pakistan, and Sri Lanka.[5] Overall, as of mid-2015 about three-quarters of all suicide attacks occurred in just three countries: Afghanistan, Pakistan, and Iraq.[6]

Suicide attacks have been described as a weapon of psychological warfare[7] to instill fear in the target population,[8] a strategy to eliminate or at least drastically diminish areas where the public feels safe, and the "fabric of trust that holds societies together".[4]

The motivation of suicide attackers varies. Kamikaze acted under military orders and were motivated by obedience and nationalism. Before 2003, most attacks targeted forces occupying the attackers' homeland, according to analyst Robert Pape.[9] Anthropologist Scott Atran states that since 2004 the overwhelming majority of bombers have been motivated by the ideology of Islamist martyrdom.[10]

Suicide attacks include both Suicide terrorism—terrorism often defined as any action "intended to cause death or serious bodily harm to civilians or non-combatants" for the purpose of intimidation[11]—and suicide attacks not targeting non-combatants. An alternative definition is provided by Jason Burke, a journalist who has lived among Islamic militants, and suggests that most define terrorism as 'the use or threat of serious violence' to advance some kind of 'cause', stressing that terrorism is a tactic.[12] Academic Fred Halliday, has written that assigning the descriptor of 'terrorist' or 'terrorism' to the actions of a group is a tactic used by states to deny 'legitimacy' and 'rights to protest and rebel'.[13]

The definition of "suicide" is another issue. Suicide terrorism itself has been defined by one source (Ami Pedahzur) as "violent actions perpetrated by people who are aware that the odds they will return alive are close to zero".[15]
Other sources[16][17] exclude from their work "suicidal" or high risk attacks, such as the Lod Airport massacre or "reckless charge in battle",[16] focusing only on true "suicide attacks", where the odds of survival are not "close to zero" but required to be zero, because "the perpetrator's ensured death is a precondition for the success of his mission".[17]

Also excluded from the definition are '

"proxy bombings", which may have political goals and may be designed to look like suicide bombing, but where the "proxy" is forced to carry a bomb under threat (such as having his/her children killed) and may be unaware they (the proxy) will be killed;[16][18][19] and

It may not always be clear to investigators which type of killing is which. Suicide attack campaigns sometimes also using proxy bombers (such as alleged in Iraq).[21] or manipulating the vulnerable to be bombers,[16][22] At least one researcher (Adam Lankford) argues that the motivation to kill and be killed connects some suicide attackers more closely to "suicidal rampage" murderers than is commonly thought.[20]

The usage of the term "suicide attack" goes back a long way[citation needed] but "suicide bombing" dates back to at least 1940 when a New York Times article mentions the term in relation to German tactics.[23] Less than two years later that newspaper referred to a Japanese kamikaze attempt on an American carrier as a "suicide bombing".[24] In 1945 The Times of London, referred to a kamikaze plane as a "suicide-bomb",[25] and two years later an article there referred to a new British pilot-less, radio-controlled rocket missile as originally designed "as a counter-measure to the Japanese 'suicide-bomber'".[26][27]

Some efforts have been made to replace the term "suicide bombing" with "homicide bombing", on the grounds that since the primary purpose of such a bombing is to kill other people, homicide is a more apt an adjective than "suicide".

Emeritus Professor Robert Goldney, of the University of Adelaide, has argued in favor of the term "homicide bomber", arguing that studies show that there is little in common between people who blow themselves up, intending to kill as many people as possible in the process, and actual suicide victims.[32] Fox News producer Dennis Murray argued that a suicidal act should be reserved for a person who does something to kill themselves only. CNN Producer Christa Robinson argued that the term "homicide bomber" reflects only that you have killed other people, but not that you have also killed yourself.[28][33]

Genocide bombing

"Genocide bombing" was coined in 2002 by Irwin Cotler, a member of the Canadian parliament, in an effort to focus attention on the alleged intention of genocide by militant Palestinians in their calls to "wipe Israel off the map".[34][35]

Sacrifice bombing

In the German-speaking area the term "sacrifice bombing" (Ger. Opferanschlag) was proposed in 2012 by German scholar Arata Takeda.[36] The term is intended to shift the focus away from the suicide of the perpetrators and towards their use as weapons by their commanders.

The 1st Century AD Jewish Sicarii sect are thought to have carried out suicidal attacks[17] against Hellenized Jews they considered immoral collaborators.[37] The Islamic Hashishiyeen (Assassins) sect of Ismaili Shi'a Muslims assassinated two caliphs, and many viziers, sultans and Crusader leaders over the course of 300 years,[38] before being annihilated by Mongol invaders. Hashishiyeen were known for their targeting of the powerful, their use of the dagger as a weapon (rather than something safer for the assassin such as a crossbow), and for making no attempt to escape after completing their killing.[39] However, this is disputed by non-orientalis scholars who claimed that unlike the Ninja or Shinobi, the Assassins always avoided suicide unless it was absolutely necessary, and preferred to be killed by their captors.

The earliest known non-military suicide attack occurred in Murchison in New Zealand on 14 July 1905. A long-standing dispute between two farmers resulted in a court case, and the defendant (Joseph Sewell) had sticks of gelignite strapped to his body. When Sewell excitedly shouted during the court sitting about the other farmer "I'll blow the devil to hell, and I have enough dynamite to do just that", he was ushered out of the building. Sewell detonated the charge when a police officer tried to arrest him on the street, and his body was blown to pieces, but nobody else died from their injuries.[40][41]

To counter the superior numbers of the Chola dynasty empire's army in the 11th century, suicide squads were raised by the Indian Chera rulers. This helped the Cheras to resist Chola invasion and maintain the independence of their kingdom from the time of Kulothunga Chola I. These warriors were known as the "chavers".[42][page needed] Later, these suicide squads rendered service as police, volunteer troop and fighting squads in the region. Now their primary duty was to assist local rulers in battles and skirmishes. The rulers of the state of Valluvanad are known to have deployed a number of suicide squads against the ruler of Calicut.[43][page needed]

In the late 17th century, Qing official Yu Yonghe recorded that injured Dutch soldiers fighting against Koxinga's forces for control of Taiwan in 1661 would use gunpowder to blow up both themselves and their opponents rather than be taken prisoner.[44] However, the Chinese observer may have confused such suicidal tactics with the standard Dutch military practice of undermining and blowing up positions recently overrun by the enemy which almost cost Koxinga his life during the Siege of Fort Zeelandia.[45]

Muslim Acehnese from the Aceh Sultanate performed suicide attacks known as Parang-sabil against Dutch invaders during the Aceh War. It was considered as part of personal jihad in the Islamic religion of the Acehnese. The Dutch called it Atjèh-moord,[46][47][48] (literally "Aceh-murder"). The Acehnese work of literature, the Hikayat Perang Sabil provided the background and reasoning for the "Aceh-mord"- Acehnese suicide attacks upon the Dutch.[49][50][51] The Indonesian translations of the Dutch terms are Aceh bodoh (Aceh pungo) or Aceh gila (Aceh mord).[52]

Atjèh-moord was also used against the Japanese by the Acehnese during the Japanese occupation of Aceh.[53] The Acehnese Ulama (Islamic clerics) fought against both the Dutch and the Japanese, revolting against the Dutch in February 1942 and against Japan in November 1942. The revolt was led by the All-Aceh Religious Scholars' Association (PUSA). The Japanese suffered 18 dead in the uprising while they slaughtered up to 100 or over 120 Acehnese.[54][55] The revolt happened in Bayu and was centred around Tjot Plieng village's religious school.[56][57][58][59] During the revolt, the Japanese troops armed with mortars and machine guns were charged by sword wielding Acehnese under Teungku Abduldjalil (Tengku Abdul Djalil) in Buloh Gampong Teungah and Tjot Plieng on 10 and 13 November.[60][61][62][63][64][65][66] In May 1945 the Acehnese rebelled again.[67]

Moro Muslims who performed suicide attacks were called mag-sabil, and the suicide attacks were known as Parang-sabil.[68] The Spanish called them juramentado. The idea of the juramentado was considered part of jihad in the Moros' Islamic religion. During an attack, a Juramentado would throw himself at his targets and kill them with bladed weapons such as barongs and kris until he himself was killed. The Moros performed juramentado suicide attacks against the Spanish in the Spanish–Moro conflict of the 16th to the 19th centuries, against the Americans in the Moro Rebellion (1899–1913), and against the Japanese in World War II.[69]

The Moro Juramentados aimed their attacks specifically against their enemies, and not against non-Muslims in general. They launched suicide attacks on the Japanese, Spanish, Americans and Filipinos, but did not attack the non-Muslim Chinese as the Chinese were not considered enemies of the Moro people.[70][71][72][73][74] The Japanese responded to these suicide attacks by massacring all known family members and relatives of the attacker(s).[75][76]

According to historian Stephan Dale, the Moro were not the only Muslims who carried out suicide attacks "in their fight against Western hegemony and colonial rule". In the 18th century, suicide tactics were used on the Malabar coast of Southwestern India, in Atjeh (Acheh) in Northern Sumatra as well.[17][77]

The first known suicide bomber was Russian.[78] The invention of dynamite in the 1860s presented revolutionary and terrorist groups in Europe with a weapon nearly twenty times more powerful than gunpowder, but with technical challenges to detonating it at the right time. One way around that obstacle was to use a human trigger, and this was the technique that assassinated Tsar Alexander II of Russia in 1881.[78][79] A would-be suicide-bomber killed Vyacheslav von Plehve, the Russian Minister of the Interior, in St Petersburg in 1904.[80]

In the Xinhai Revolution, many Chinese revolutionaries became martyrs in battle. "Dare to Die" student corps were founded, for student revolutionaries wanting to fight against Qing dynasty rule. Dr. Sun Yatsen and Huang Xing promoted the Dare to Die corps. Huang said, "We must die, so let us die bravely."[83] Suicide squads were formed by Chinese students going into battle, knowing that they would be killed fighting against overwhelming odds.[84]

The 72 Martyrs of Huanghuagang died in the uprising that began the Wuchang Uprising, and were recognized as heroes and martyrs by the Kuomintang party and the Republic of China.[85] The martyrs in the Dare to Die Corps who died in battle wrote letters to family members before heading off to certain death. The Huanghuakang was built as a monument to the 72 martyrs.[86] The deaths of the revolutionaries helped the establishment of the Republic of China, overthrowing the Qing dynasty imperial system.[87] Other Dare to Die student corps in the Xinhai revolution were led by students who later became major military leaders in Republic of China, like Chiang Kai-shek,[88] and Huang Shaoxiong with the Muslim Bai Chongxi against Qing dynasty forces.[89][90][91]
"Dare to Die" troops were used by warlords.[92] The Kuomintang used one to put down an insurrection in Canton.[93] Many women joined them in addition to men to achieve martyrdom against China's opponents.[94][95] They were known as 烈士 "Lit-she" (Martyrs) after accomplishing their mission.[96]

Suicide bombing was also used against the Japanese. A "dare to die corps" was effectively used against Japanese units at the Battle of Taierzhuang.[98] They used swords.[99][100] They wore suicide vests made out of grenades.[101][102]

During the 1946–1950 Communist Revolution, coolies fighting the Communists formed "Dare to Die Corps" to fight for their organizations, with their lives.[111] During the Tiananmen Square Incident of 1989, protesting students also formed "Dare to Die Corps", to risk their lives defending the protest leaders.[112]

Kamikaze, a ritual act of self-sacrifice carried out by Japanese pilots of explosive-laden aircraft against Allied warships, occurred on a large scale at the end of World War II. About 3000 attacks were made and about 50 ships were sunk.[113]

Later in the war, as Japan became more desperate, this act became formalized and ritualized, as planes were outfitted with explosives specific to the task of a suicide mission.[114] Kamikaze strikes were a weapon of asymmetric war used by the Empire of Japan against United States Navy and Royal Navyaircraft carriers, although the armoured flight deck of the Royal Navy carriers diminished Kamikaze effectiveness. The Japanese Navy also used piloted torpedoes called kaiten ("Heaven shaker") on suicide missions. Although sometimes called midget submarines, these were modified versions of the unmanned torpedoes of the time and are distinct from the torpedo-firing midget submarines used earlier in the war, which were designed to infiltrateshore defenses and return to a mother ship after firing their torpedoes. Although extremely hazardous, these midget submarine attacks were not technically suicide missions, as the earlier midget submarines had escape hatches. Kaitens, however, provided no means of escape.[115][116]

During the Battle for Berlin the Luftwaffe flew "Self-sacrifice missions" (Selbstopfereinsatz) against Soviet bridges over the River Oder. These 'total missions' were flown by pilots of the Leonidas Squadron. From April 17–20, 1945, using any available aircraft, the Luftwaffe claimed the squadron had destroyed 17 bridges, however military historian Antony Beevor when writing about the missions thinks that this was exaggerated and that only the railway bridge at Küstrin was definitely destroyed. He comments that "thirty-five pilots and aircraft was a high price to pay for such a limited and temporary success". The missions were called off when the Soviet ground forces reached the vicinity of the squadron's airbase at Jüterbog.[117]

North Korean tanks were attacked by South Koreans with suicide tactics during the Korean War.[119][120]

American tanks at Seoul were attacked by North Korean suicide squads,[121] who used satchel charges.[122] North Korean soldier Li Su-Bok is considered a hero for destroying an American tank with a suicide bomb.[123]

An Arab Christian military officer from Syria, Jules Jammal, allegedly brought down a French ship with a suicide attack during the Suez Crisis in 1956[124] according to Egyptian media, although both French ships with that name were unharmed during the crisis.[125]

On December 27th, 2018, the Green Bay Press-Gazette interviewed veteran Mark Bentley, who had trained for the Special Atomic Demolition Munition program to manually place and detonate a modified version of the W54 nuclear bomb. The report stated that he and other soldiers training for the program knew this was a suicide mission because either because it would be unrealistic to outrun the timer on the bomb, or that soldiers would be obligated to secure the site before the timer went off. However, in theory the timer could be set long enough to give the team a chance to escape. Specifically, he stated, "We all knew it was a one-way mission, a suicide mission." [126] "You set your timer, and it would click when it went off, or it went ding or I forget what, but you knew you were toast," he said. "Ding! Your toast is ready, and it's you." He also commented, "The Army is not going to set a bomb like that and run away and leave it, because they don't know if someone else would get ahold of it," he said. "They have to leave troops there to make sure it's not stolen or compromised, and that would just be collateral damage. You didn't go out with the thought that it was anything other than a one-way mission. If you're Bruce Willis, you get away, but I ain't Bruce Willis."[126]

The concept of self-sacrifice as a means to killing others dates back to antiquity with Samson's suicidal mass killing of the Philistine leaders,[127] but the idea of suicide bombing "as a tool of stateless terrorists" was only "dreamed up a hundred years ago by the European anarchists",[128] according to author Noah Feldman.[129] It was not until 1983 when Shiite militants blew up the U.S. Marine barracks in Lebanon, that it became "tool of modern terrorist warfare".[129]
Modern suicide bombing has been defined as "involving explosives deliberately carried to the target either on the person or in a civilian vehicle and delivered by surprise".[130] (Noah Feldman and many others exclude terror attacks such as the Lod Airport massacre where "the perpetrator's ensured death" was not "a precondition for the success of his mission".[17]) The intended targets are often civilian, not just military or political.

Another non-religious group involved in suicide attacks was the Kurdistan Workers' Party which began their insurgency against the Turkish state in 1984. According to the Chicago Project on Security and Terrorism's Suicide Attack Database, as of 2015, ten suicide attacks by the PKK from 1996 to 2012 killed 32 people and injured 116.[146] (Suicide attacks are only part of the PKK's militant arsenal as they have killed or wounded hundreds of government workers and destroyed or damaged hundreds of school, post offices and mosques.[147])

In early 2000, one analyst (Yoram Schweitzer) saw a pause in bombing campaigns and argued that "most of the groups that were involved in suicide terrorism either stopped using it or eventually reduced it significantly."[17]

The number of attacks using suicide tactics grew from an average of fewer than five per year during the 1980s to 81 suicide attacks in 2001 to 460 in 2005.[150] By 2005, the tactic had spread to dozens of countries.[151]

These bombings have tended to have more popular support than in other Muslim countries, and more music videos and announcements that promise eternal reward for suicide bombers can be found on Palestinian television (according to Palestinian Media Watch).[156][157] Israeli sources alleged that Hamas, Islamic Jihad and Fatah operate "Paradise Camps", training children as young as 11 to become suicide bombers.[158][159]

The September 11, 2001 attacks, orchestrated by al-Qaeda, has been called "the worst attack on American soil since the Japanese attack on Pearl Harbor which thrust the United States into World War II".[160] They involved the hijacking of four large passenger jet airliners because their long transcontinental flight plans meant they carried more fuel, allowing a bigger explosion on impact (unlike earlier airline hijackings, the primary focus was the planes, not the passengers).[78] Two planes were deliberately flown into the Twin Towers of the World Trade Center in New York City, destroying both 110 story skyscrapers within less than two hours, and a third was flown into the Pentagon in Arlington County, Virginia, causing severe damage to the west side of the building. These attacks resulted in the deaths of 221 people (including the 15 hijackers) on board the three planes as well as 2,731 more in and around the targeted buildings.[161] A fourth plane crashed into a field near Shanksville, Pennsylvania, after a revolt by the plane's passengers, killing all 44 people (including the four hijackers) on board. In total, the attacks killed 2,996 people and injured more than 6,000 others. The U.S. stock market closed for four trading days after the attacks (the first time it had an unscheduled closing since the Great Depression).[162] Nine days after the attack, U.S. PresidentGeorge W. Bush called for a "War on Terror" and shortly thereafter launched the War in Afghanistan to find and capture Osama bin Laden, the head of the al-Qaeda organization that mounted the 9/11 attacks.[162]

In addition to United States military targets, they attacked many civilian targets such as Shiitemosques, international offices of the UN and the Red Cross. Iraqi men waiting to apply for jobs with the new army and police force were targets. In the lead up to the Iraqi parliamentary election, on January 30, 2005, suicide attacks upon civilian and police personnel involved with the elections increased. There were also reports of the insurgents co-opting disabled people as involuntary suicide bombers.[163]

Other major locations of suicide attack are Afghanistan (1,059 attacks as of mid-2015)[6] and Pakistan (490 attacks).[6] In the first eight months of 2008, Pakistan overtook Iraq and Afghanistan in suicide bombings, with 28 bombings killing 471 people.[164]
Suicide bombings have become a tactic in Chechnya, first being used in the conflict in 2000 in Alkhan Kala,[165]
and spreading to Russia, notably with the Moscow theater hostage crisis in 2002 to the Beslan school hostage crisis in 2004.[166]

In Europe four Islamist suicide bombers exploded home-made peroxide explosives on three London underground trains and a bus on 7 July 2005, during the morning rush hour. These "7/7" bombings killed 52 civilians and injured 700.[167]

Since 2006, al-Shabaab and its predecessor, the Islamic Courts, have carried out major suicide attacks in Somalia,[168][169] the worse year so far being 2014 with 16 attacks and over 120 killed.

According to author Jeffrey William Lewis, to succeed, campaigns of suicide bombing need:

willing individuals

organizations to train and use them

a society willing to accept such acts in the name of a greater good[78]

The organizations work to guarantee individual suicide bombers that they "will be remembered as martyrs dying for their communities". By imbuing suicide bombing/attacks with "reverence and heroism", it becomes more attractive to recruits.[78]
According to Yoram Schweitzer, modern suicide terrorism is "aimed at causing devastating physical damage, through which it inflicts profound fear and anxiety". Its goal is not to produce a negative psychological effect only on the victims of the actual attack, but on the entire target population.[17]
Attackers themselves have often framed suicide attacks as acts of courageous self-sacrifice in made necessary by the superior military or security strength of the enemy. The technique has also been called "the atomic weapon of the weak".[174] According to Sheikh Ahmed Yassin, the former leader of Hamas, "Once we have warplanes and missiles, then we can think of changing our means of legitimate self-defense. But right now, we can only tackle the fire with our bare hands and sacrifice ourselves."[175] While arguably this explains the motivation of many early suicide bombings in the 1980s and 90s, it cannot explain many later attacks, such as on funeral processions of the minority Shia in Pakistan.

A major reason for the popularity of suicide attacks despite the sacrifice involved for its perpetrators is its tactical advantages over other types of terrorism. The ability to conceal weapons, make last-minute adjustments, increased ability to infiltrate heavily guarded targets, lack of need for remote or delayed detonation, escape plans or rescue teams. Robert Pape observes: "Suicide attacks are an especially convincing way to signal the likelihood of more pain to come, because if you are willing to kill yourself you are also willing to endure brutal retaliation. "... The element of suicide itself helps increase the credibility of future attacks because it suggests that attackers cannot be deterred."[176]

Bruce Hoffman describes the characteristics of suicide bombing, as "universal": "Suicide bombings are inexpensive and effective. They are less complicated and compromising than other kinds of terrorist operations. They guarantee media coverage. The suicide terrorist is the ultimate smart bomb. Perhaps most important, coldly efficient bombings tear at the fabric of trust that holds societies together."[177]

Studies of who becomes a suicide attacker and what motivates them have often come to different conclusions.
According to Riaz Hassan, "apart from one demographic attribute – that the majority of suicide bombers tend to be young males – the evidence has failed to find a stable set of demographic, psychological, socioeconomic and religious variables that can be causally linked to suicide bombers’ personality or socioeconomic origins."[5] Scott Atran agrees: "In targeting potential recruits for suicide terrorism, it must be understood that terrorist attacks will not be prevented by trying to profile terrorists. They are not sufficiently different from everyone else. Insights into homegrown jihadi attacks will have to come from understanding group dynamics, not individual psychology. Small-group dynamics can trump individual personality to produce horrific behavior in otherwise ordinary people."[3] Reasons vary greatly, and are different in the case of each individual. Fanaticism (nationalist or religious, or both), results from brain-washing, negative experiences regarding “the enemy”, the lack of a perspective in life. Suicides want to hurt or kill their targets because they hold them responsible for all bad things that has happened to them or in the world or simply just because they want to escape misery and poverty.[178]

Based on biographies of more than seven hundred foreign fighters uncovered at an Iraqi insurgent camp, researchers believe that the motivation for suicide missions (at least in Iraq) was not "the global jihadi ideology", but "an explosive mix of desperation, pride, anger, sense of powerlessness, local tradition of resistance and religious fervor".[179]

Criminal Justice professor Adam Lankford argues that suicide terrorists are not psychologically normal or stable, and are motivated to suicide/killing to mask their desire to die beneath a "veneer of heroic action", because of the religious consequences of killing themselves outright.[180] He has identified more than 130 individual suicide terrorists, including 9/11 ringleader Mohamed Atta, with classic suicidal risk factors, such as depression, post-traumatic stress disorder, other mental health problems, drug addictions, serious physical injuries or disabilities, or having suffered the unexpected death of a loved one or from other personal crises.[181]

A study of the remains of 110 suicide bombers in Afghanistan for the first part of 2007 by Afghan pathologist Dr. Yusef Yadgari, found 80% were suffering from physical aliments such as missing limbs (before the blasts), cancer, or leprosy. Also in contrast to earlier findings of suicide bombers, the Afghan bombers were "not celebrated like their counterparts in other Arab nations. Afghan bombers are not featured on posters or in videos as martyrs."[182]

AnthropologistScott Atran's research has found that the attacks are not organized from the top down, but occurs from the bottom up. That is, it is usually a matter of following one's friends, and ending up in environments that foster groupthink. Atran is also critical of the claim that terrorists simply crave destruction; they are often motivated by beliefs they hold sacred, as well as their own moral reasoning.[183]

Robert Pape, director of the Chicago Project on Suicide Terrorism, found the majority of suicide bombers came from the educated middle classes. (Humam Balawi, who perpetrated the Camp Chapman attack in Afghanistan in 2010, was a medical doctor.[184])
A 2004 paper by Harvard University Professor of Public Policy Alberto Abadie "cast[s] doubt on the widely held belief that terrorism stems from poverty, finding instead that terrorist violence (not just suicide terrorism) is "related to a nation's level of political freedom", with countries "in some intermediate range of political freedom" more prone to terrorism than countries
with "high levels" of political freedom or countries with "highly authoritarian regimes". "When governments are weak, political instability is elevated, so conditions are favorable for the appearance of terrorism".[185][186]

A study by German scholar Arata Takeda analyzes analogous behavior represented in literary texts from the antiquity through the 20th century (Sophocles' s Ajax, Milton's Samson Agonistes, Friedrich Schiller's The Robbers, Albert Camus's The Just Assassins) and comes to the conclusion "that suicide bombings are not the expressions of specific cultural peculiarities or exclusively religious fanaticisms. Instead, they represent a strategic option of the desperately weak who strategically disguise themselves under the mask of apparent strength, terror, and invincibility."[187][188]

To what extent attackers are motivated by religious enthusiasm, by resistance to perceived outsider oppression or some combination of the two is disputed.

According to Robert Pape, director of the Chicago Project on Suicide Terrorism, as of 2005, 95% of suicide attacks have the same specific strategic goal: to cause an occupying state to withdraw forces from a disputed territory, making nationalism not religion their principal motivation.[189]

Beneath the religious rhetoric with which [such terror] is perpetrated, it occurs largely in the service of secular aims. Suicide terrorism is mainly a response to foreign occupation rather than a product of Islamic fundamentalism ... Though it speaks of Americans as infidels, al-Qaida is less concerned with converting us to Islam than removing us from Arab and Muslim lands.[190]

Alternately, another source found that at least in one country (Lebanon from 1983–1999) it was Islamists who influenced secular nationalists—their use of suicide attack spreading to the secular groups. Five Lebanese groups "espousing a non-religious nationalist ideology" followed the lead of Islamist groups in attacking by suicide, "impressed by the effectiveness of Hezbollah's attacks in precipitating the withdrawal of the 'foreigners' from Lebanon".[17] (In Israel suicide attacks by Islamist Islamic Jihad and Hamas also preceded those of the secular PFLP and the Al-Fatah-linked Al-Aqsa Martyrs' Brigades.)

Pape found other factors associated with suicide attacks included

the government of the targeted country being democratic and the public opinion of the country playing a role in determining policy.

Other researchers contend that Pape's analysis is flawed, particularly his contention that democracies are the main targets of such attacks.[195]
Atran argues that suicide bombing has moved on from the days of Pape's study,[192] that non-Islamic groups have carried out very few bombings since 2003, while bombing by Muslim or Islamist groups associated with a "global ideology" of "martyrdom" has skyrocketed. In one year, in one Muslim country alone – 2004 in Iraq – there were 400 suicide attacks and 2,000 casualties.[10] Other researchers (such as Yotam Feldner) argue that perceived religious rewards in the hereafter are instrumental in encouraging Muslims to commit suicide attacks,[196][197] or ask why prominent secular anti-occupation terrorist groups—such as the Provisional IRA, ETA or anti-colonialist insurgents in Vietnam, Algeria, etc.[198]—have not used suicide,[199] why he does not mention that the very first suicide attack in Lebanon (in 1981) targeted the embassy of Iraq, a country which was not occupying Lebanon.[198]

Mia Bloom agrees with Pape that competition among insurgents groups is a significant motivator, arguing the growth in suicide as a tactic is a product of "outbidding", i.e. the need by competing insurgent groups to demonstrate their commitment to the cause to broader public—making the ultimate sacrifice for the insurgency being a "bid" impossible to top.[200] (This explains its use by Palestinian groups, but not that by the Tamil Tigers.[199])
Still other researchers have identified sociopolitical factors as more central in the motivation of suicide attackers than religion.[201][202]

According to Atran[203] and former CIA case officer Marc Sageman,[204] support for suicide actions is triggered by moral outrage at perceived attacks against Islam and sacred values, but this is converted to action as a result of small-world factors (such as being part of a football club with other jihadis). Millions express sympathy with global jihad (according to a 2006 Gallup study involving more than 50,000 interviews in dozens of countries, 7 percent or at least 90 million of the world's 1.3 billion Muslims consider the 9/11 attacks "completely justified").[205][206]

Afghanistan suicide bomb attacks, including non-detonated, 2002–2008

Also arguing that the increase in suicide terrorism since 2001 is really driven by Salafi/Jihadist ideology and Al-Qaeda is Assaf Moghadam.[207][208]

Updating his work in a 2010 book Cutting the Fuse, Pape reported that a fine-grained analysis of the time and location of attacks strongly support his conclusion that "foreign military occupation accounts for 98.5% – and the deployment of American combat forces for 92% – of all the 1,833 suicide terrorist attacks around the world" between 2004 and 2009[209][210] Moreover, "the success attributed to the surge in 2007 and 2008 was actually less the result of an increase in coalition forces and more to a change of strategy in Baghdad and the empowerment of the Sunnis in Anbar." (emphasis in the original)[211][212]

The same logic can be seen in Afghanistan. In 2004 and early 2005, NATO occupied the north and west, controlled by the Northern Alliance, whom NATO had previously helped fight the Taliban. An enormous spike in suicide terrorism only occurred later in 2005 as NATO moved into the south and east, which had previously been controlled by the Taliban and locals were more likely to see NATO as a foreign occupation threatening local culture and customs.[213][214] Critics argue the logic cannot be seen in Pakistan,[198][215] which has no occupation and the second highest number of suicide bombing fatalities as of mid-2015.

What connection the high percentage of suicide attacks executed by Islamist groups since 1980 has to do with the religion of Islam is disputed. Specifically, scholars, researchers, and others, disagree over whether Islam forbids suicide in the process of attacking enemies or the killing of civilians. According to a report compiled by the Chicago Project on Suicide Terrorism, 224 of 300 suicide terror attacks from 1980 to 2003 involved Islamist groups or took place in Muslim-majority lands.[216] Another tabulation found more than a fourfold increase in suicide bombings in the two years following Papes study and that the overwhelming majority of these bombers were motivated by the ideology of Islamist martyrdom.[10] (For example, as of early 2008, 1,121 Muslim suicide bombers have blown themselves up in Iraq.[217])

Islamic suicide bombing is a fairly recent event. It was totally absent from the 1979–1989 Afghan jihad against the Soviet Union,[129] (an asymmetrical war where the mujahideen fought Soviet warplanes, helicopters and tanks primarily with light weapons). According to author Sadakat Kadri, "the very idea that Muslims might blow themselves up for God was unheard of before 1983, and it was not until the early 1990s that anyone anywhere had tried to justify killing innocent Muslims who were not on a battlefield." After 1983 the process was limited among Muslims to Hezbollah and other Lebanese Shi'a factions for more than a decade.[218]

Since then, the "vocabulary of martyrdom and sacrifice", videotaped pre-confession of faith by attackers have become part of "Islamic cultural consciousness", "instantly recognizable" to Muslims (according to Noah Feldman),[129] while the tactic has spread through the Muslim world "with astonishing speed and on a surprising course".[129]

First the targets were American soldiers, then mostly Israelis, including women and children. From Lebanon and Israel, the technique of suicide bombing moved to Iraq, where the targets have included mosques and shrines, and the intended victims have mostly been ShiiteIraqis. ... [In] Afghanistan, ... both the perpetrators and the targets are orthodox Sunni Muslims. Not long ago, a bombing in Lashkar Gah, the capital of Helmand Province, killed Muslims, including women, who were applying to go on pilgrimage to Mecca. Overall, the trend is definitively in the direction of Muslim-on-Muslim violence. By a conservative accounting, more than three times as many Iraqis have been killed by suicide bombings in just three year (2003–6) as have Israelis in ten (from 1996–2006). Suicide bombing has become the archetype of Muslim violence – not just to Westerners but also to Muslims themselves.[129]

Recent research on the rationale of suicide bombing has identified both religious and sociopolitical motivations.[219][220][221][222] Those who cite religious factors as an important influence note that religion provides the framework because the bombers believe they are acting in the name of Islam and will be rewarded as martyrs. Since martyrdom is seen as a step towards paradise, those who commit suicide while discarding their community from a common enemy believe that they will reach an ultimate salvation after they die.[219]

In the media attention given to suicide bombing during the Second Intifada and after 9/11, sources hostile to radical Islamism quoted radical scholars promising various heavenly rewards, such as 70 virgins (houri) as wives, to Muslims who die as martyrs, (specifically as suicide attackers).[223][224][225][226] One Israeli source (Y. Feldner of MEMRI) complained that

the death announcements of martyrs in the Palestinian press often take the form of wedding, not funeral, announcements. `Blessings will be accepted immediately after the burial and until 10 p.m. ...at the home of the martyr's uncle,` read one suicide bomber's death notice.[227] `With great pride, the Palestinian Islamic Jihad marries the member of its military wing... the martyr and hero Yasser Al-Adhami, to "the black-eyed,"` read another.[225][228]

Other alleged rewards for those dying in jihad are feeling no pain from the cause of their death,[225] being cleansed of all sin and brought directly to paradise, not having to wait for the Day of Judgement.[229][230][231]

Others (such as As'ad AbuKhalil) maintain that "the tendency to dwell on the sexual motives" of the suicide bombers "belittles" the bombers "sociopolitical causes", and that the alleged "sexual frustration" of young Muslim men "has been overly emphasized in the Western and Israeli media" as a motive for terrorism.[202]

Support for "martyrdom operations"

Islamist militant organisations (including al-Qaeda, Hamas and Islamic Jihad) argue that despite what some Muslims claim is Islam's strict prohibition of suicide and murder,[232][233]
suicide attacks fulfill the obligation of jihad against the "oppressor", "martyrs" will be rewarded with paradise, and have the support of (some) Muslim clerics.
Clerics have supported suicide attacks largely in connection with the Palestinian issue. Prominent Sunni cleric Yusuf al-Qaradawi previously had supported such attacks by Palestinians in perceived defense of their homeland as heroic and an act of resistance.[234] Shiite Lebanese cleric Muhammad Husayn Fadlallah, the spiritual authority recognized by Hezbollah, holds similar views.[129]
According to the conservative Iranian Shi'ah cleric Ayatollah Mohammad Taghi Mesbah Yazdi, "When protecting Islam and the Muslim community depends on martyrdom operations, it not only is allowed, but even is an obligation as many of the Shi'ah great scholars and Maraje', including AyatullahSafi Golpayegani and Ayatullah Fazel Lankarani, have clearly announced in their fatwas."[235]

The Quranic verse used by Zarein Ahmedzay (an Afghanistan-born New York City cab driver who traveled to Waziristan for terrorist training and discussed possible suicide bombing target locations in crowded parts of Manhattan) in support of his actions was 9:111 (Surah At-Tawba):[236]

Verily, Allah has purchased of the believers their lives and their wealth for the price of Paradise, to fight in the way of Allah, to kill and be killed. It is a promise binding on the truth in the Torah, the Gospel and the Qur'an.[237]

Supporters of the Taliban insist their attacks are "martyrdom operations" and not suicide. The June 2013 issue of the Taliban magazine Azan extolled the virtues of suicide attacks, claiming that "suicide bombing" is a "false term" for jihad martyrdom attacks. "So martyrdom operation ≠ Suicide bombing".[238]

The articles maintains that Abu Huraira (a companion of the Muhammad) and Umar ibn Khattab (the third caliph of Islam), approved acts in which the Muslims knew would lead to certain death, and that the Islamic prophet Muhammad also approved of such acts (according to authors Maulana Muawiya Hussaini and Ikrimah Anwar cited numerous Hadith of Muhammad on the authority of Islamic jurist Muslim ibn al-Hajjaj). "The Sahaba [companions of the Islamic prophet Muhammad] who carried out the attacks almost certainly knew that they were going to be killed during their operations but they still carried them out and such acts were extolled and praised in the sharia."[239]

... a clear difference was made between throwing oneself to certain death at the hands of an overwhelmingly strong enemy, and dying by one's own hand. The first, if conducted in a properly authorized [ jihad ], was a passport to heaven; the second to damnation. The blurring of their previously vital distinction was the work of some twentieth-century theologians who outlined the new theory which the suicide bombers put into practice."[39]

The difference between engaging in an act where the perpetrator plans to fight to the death but where the attack does not require their death, is important to at least one Islamist terror group – Lashkar-e-Taiba (LeT). While the group extols "martyrdom" and has killed many civilians, LeT believes suicide attacks where the attackers dies by their own hand (such as by pressing a detonation button), are haram (forbidden). Its "trademark" is that of perpetrators fighting "to the death" but escaping "if practical". "This distinction has been the subject of extensive discourse among radical Islamist leaders."[240]

A number of Western and Muslim scholars of Islam have posited that suicide attacks are a clear violation of classical Islamic law and characterized such attacks against civilians as murderous and sinful.[241][242]

According to Bernard Lewis, "the emergence of the now widespread terrorism practice of suicide bombing is a development of the 20th century. It has no antecedents in Islamic history, and no justification in terms of Islamic theology, law, or tradition."[242] Islamic legal rules of armed warfare or military jihad are covered in detail in the classical texts of Islamic jurisprudence,[129] which forbidding the killing of women, children or non-combatants, and the destroying of cultivated or residential areas.[129][243][244]
For more than a millennium, these tenets were accepted by Sunnis and Shiites; however, since the 1980s militant Islamists have challenged the traditional Islamic rules of warfare to justify suicide attacks.[129][243]

A number of respected Muslim scholars have provided scholastic refutations of suicide bombings, condemning them as terrorism prohibited in Islam and leading their perpetrators to hell.[241] In his 400+ page Fatwa on Terrorism condemning suicide attacks, Muslim Islamic scholar Muhammad Tahir-ul-Qadri directly disputed the rationale of Islamists, arguing among other things that the indiscriminately killing of both Muslims and non-Muslims is unlawful, and brings the Muslim ummah into disrepute, no matter how lofty the killers intentions.[245] Tahir-ul-Qadri states terrorism "has no place in Islamic teaching, and no justification can be provided to it...good intention cannot justify a wrong and forbidden act".[241]

The Grand Mufti of Saudi Arabia, Abdul-Aziz ibn Abdullah Al Shaykh, issued a fatwa on September 12, 2013 that suicide bombings are "great crimes" and bombers are "criminals who rush themselves to hell by their actions". Al Shaykh described suicide bombers as "robbed of their minds... who have been used (as tools) to destroy themselves and societies".[246]

"In view of the fast-moving dangerous developments in the Islamic world, it is very distressing to see the tendencies of permitting or underestimating the shedding of blood of Muslims and those under protection in their countries. The sectarian or ignorant utterances made by some of these people would benefit none other than the greedy, vindictive and envious people. Hence, we would like to draw attention to the seriousness of the attacks on Muslims or those who live under their protection or under a pact with them", Al Shaykh said, quoting a number of verses from the Qur'an and Hadith.[247]

Ihsanic Intelligence, a London-based Islamic think-tank, published their two-year study into suicide bombings in the name of Islam, The Hijacked Caravan,[252] which concluded that,

The technique of suicide bombing is anathema, antithetical and abhorrent to Sunni Islam. It is considered legally forbidden, constituting a reprehensible innovation in the Islamic tradition, morally an enormity of sin combining suicide and murder and theologically an act which has consequences of eternal damnation.[253]

The classical jurists, nearly without exception, argued that those who attack by stealth, while targeting noncombatants in order to terrorize the resident and wayfarer, are corrupters of the earth. "Resident and wayfarer" was a legal expression that meant that whether the attackers terrorize people in their urban centers or terrorize travelers, the result was the same: all such attacks constitute a corruption of the earth. The legal term given to people who act this way was muharibun (those who wage war against society), and the crime is called the crime of hiraba (waging war against society). The crime of hiraba was so serious and repugnant that, according to Islamic law, those guilty of this crime were considered enemies of humankind and were not to be given quarter or sanctuary anywhere .... Those who are familiar with the classical tradition will find the parallels between what were described as crimes of hiraba and what is often called terrorism today nothing short of remarkable. The classical jurists considered crimes such as assassinations, setting fires, or poisoning water wells – that could indiscriminately kill the innocent – as offenses of hiraba. Furthermore, hijacking methods of transportation or crucifying people in order to spread fear are also crimes of hiraba. Importantly, Islamic law strictly prohibited the taking of hostages, the mutilation of corpses, and torture.[254]

According to Charles Kimball, chair of the Department of Religion at Wake Forest University, "There is only one verse in the Qur'an that contains a phrase related to suicide" (4:29):[255]

O you who have believed, do not consume one another's wealth unjustly but only [in lawful] business by mutual consent. And do not kill yourselves. Indeed, Allah is to you ever Merciful.[256]

Some commentators posit that "do not kill yourselves" is better translated "do not kill each other", and some translations (e.g., by M.H. Shakir) reflect that view. Mainstream Islamic groups such as the European Council for Fatwa and Research also cite the Quranic verse Al-An'am 6:151[257])] as prohibiting suicide: "And take not life, which Allah has made sacred, except by way of justice and law".[258] The Hadith, including Bukhari 2:445, states: "The Prophet said, '...whoever commits suicide with a piece of iron will be punished with the same piece of iron in the Hell Fire', [and] 'A man was inflicted with wounds and he committed suicide, and so Allah said: 'My slave has caused death on himself hurriedly, so I forbid Paradise for him.'"[259][260]

Other Muslims have also noted Quranic verses in opposition to suicide, to taking of life other than by way of justice (i.e. the death penalty for murder), and to collective punishment.[261]

Results of Pew Research Center survey asking Muslims the question: "Suicide bombing can be ______ justified against civilian targets in order to defend Islam from its enemies?" Percentage of respondents choosing "often" or "sometimes", rather than "rarely" or "never".[265][266][267]

Support by Muslims for "suicide bombing and other forms of violence that target civilians in order to defend Islam", has varied over time and by country. The Pew Global Attitudes Project survey of the Muslim public found support has declined over the years (on average) from a post-9/11 high. The highest support for such acts has been reported in the occupied Palestinian territories where in 2014 46% of Muslims in Palestine thought such attacks were sometimes/oftentimes justified.[267]

Female suicide bombers have been observed in many predominantly nationalist conflicts by a variety of organizations against both military and civilian targets. In February 2002, however, Sheikh Ahmed Yassin, the religious leader of Hamas, issued a fatwa, giving women permission to participate in suicide attacks.[270]

During the 1980s the greatest number of female suicide attacks in any single year was five. By contrast, in 2008 alone there were 35 female suicide attacks and in 2014 there were 15 such attacks according to the Chicago Project on Security and Terrorism (CPOST) Suicide Attack Database.[271][272]

On February 27, 2002, Darine Abu Aisha carried out a suicide bombing at the Maccabim checkpoint of the Israeli army near Jerusalem. On the same day, Sheikh Ahmed Yassin, the religious leader of the Palestinian Islamist militant group Hamas, issued a fatwa, or religious rule, that gave women permission to participate in suicide attacks, and stated that they would be rewarded in the afterlife.[270]:315

Ayat al-Akhras, the third and youngest Palestinianfemale suicide bomber (at age 18), killed herself and two Israeli civilians on March 29, 2002 by detonating explosives belted to her body in a supermarket. She had been trained by the Al-Aqsa Martyrs' Brigades, a group linked to the armed branch of Fatah (Yasser Arafat's party), more secular than Hamas. The killings gained widespread international attention due to Ayat's age and gender and the fact that one of the victims was also a teenage girl.

Two female attackers attacked U.S. troops in Iraq on August 5, 2003. Whereas female suicide bombers are not typically introduced in initial stages of a conflict, this attack demonstrates the early and significant involvement of Iraqi women in the Iraq War.[276]:284

The Taliban has used at least one female suicide bomber in Afghanistan.[277]

On December 25, 2010, the first female suicide bomber in Pakistan detonated her explosives-laden vest, killing at least 43 people at an aid distribution center in northwestern Pakistan.[278]

On December 29, 2013, a female Chechen suicide bomber detonated her vest in the Volgograd railway station killing at least 17 people.[279]

On December 23, 2016, the first female suicide bomber in Bangladesh detonated her explosive during a police raid.[280]

According to a report issued by intelligence analysts in the U.S. army in 2011, "Although women make up roughly 15% of the suicide bombers within groups which utilize females, they were responsible for 65% of assassinations; 20% of women who committed a suicide attack did so with the purpose of assassinating a specific individual, compared with 4% of male attackers." The report further stated that female suicide bombers often were "grieving the loss of family members [and] seeking revenge against those they feel are responsible for the loss, unable to produce children, [and/or] dishonored through sexual indiscretion."[281][282]
Male suicide bombers are presented as being motivated more by political factors than female suicide bombers are.[283]

Another study of suicide bombers from 1981 and July 2008 by Lindsey A. O’Rourke found female bombers are generally in their late twenties, significantly older than their male counterparts.[284]

O’Rourke found the average number of victims killed by a female suicide attacker was higher than that for male attackers for every group studied (Tamil, PKK, Lebanese, Chechen, Palestinian[285]). Consequently, terrorist organizations recruit and motivate women to participate in suicide attacks, using traditional attitudes of honor and feminine harmlessness and vulnerability among target populations to insert attackers were they can cause a maximum of death and destruction.[284] Bombs have been disguised as a pregnant belly, avoiding invasive searches, seen as taboo. By stumbling or calling out in distress more victims may be drawn to the explosion.[284] These women have proven to be more deadly with higher success rates with more casualties and deaths than their male counterparts. The woman bomber carriers are not permitted to hold and control the detonator, which are still held by the men in charge.[284] Until recently, attacks of women bombers were considered more newsworthy because of the "unladylike" behavior of their perpetrator.[286]

Studies have attempted to learn the history and motivation of suicide attackers.

Al Qaeda

Analysis of the 9/11 Al Qaeda attackers found almost all had joined the group with someone else. About 70 percent joined with friends, 20 percent with kin. Interviews with friends of the 9/11 pilots reveal they weren't "recruited" into Qaeda. They were Middle Eastern Arabs isolated even among the Moroccan and Turkish Muslims who predominate in Germany. Seeking friendship, they began hanging out after services at the Masjad al-Quds and other nearby mosques in Hamburg, in local restaurants and in the dormitory of the Technical University in the suburb of Harburg. Three (Mohamed Atta, Ramzi bin al-Shibh, Marwan al-Shehhi) wound up living together as they self-radicalized. They wanted to go to Chechnya, then Kosovo.[287]

Hamas

Bus after 2003 suicide bombing in Haifa

Hamas's most sustained suicide bombing campaign in 2003–04 involved several members of Hebron's Masjad (mosque) al-Jihad soccer team. Most lived in the Wad Abu Katila neighborhood and belonged to the al-Qawasmeh hamula (clan); several were classmates in the neighborhood's local branch of the Palestinian Polytechnic College. Their ages ranged from 18 to 22. At least eight team members were dispatched to suicide shooting and bombing operations by the Hamas military leader in Hebron, Abdullah al-Qawasmeh (killed by Israeli forces in June 2003 and succeeded by his relatives Basel al-Qawasmeh, killed in September 2003, and Imad al-Qawasmeh, captured on October 13, 2004). In retaliation for the assassinations of Hamas leaders Sheikh Ahmed Yassin (March 22, 2004) and Abdel Aziz al-Rantissi (April 17, 2004), Imad al-Qawasmeh dispatched Ahmed al-Qawasmeh and Nasim al-Ja'abri for a suicide attack on two buses in Beer Sheva (August 31, 2004). In December 2004, Hamas declared a halt to suicide attacks.[287]

On January 15, 2008, the son of Mahmoud al-Zahar, the leader of Hamas in the Gaza Strip, was killed (another son was killed in a 2003 assassination attempt on Zahar). Three days later, Israel Defense Minister Ehud Barak ordered Israel Defense Forces to seal all border crossings with Gaza, cutting off the flow of supplies to the territory in an attempt to stop rocket barrages on Israeli border towns. Nevertheless, violence from both sides only increased. On February 4, 2008, two friends (Mohammed Herbawi, Shadi Zghayer), who were members of the Masjad al-Jihad soccer team, staged a suicide bombing at commercial center in Dimona, Israel. Herbawi had previously been arrested as a 17-year-old on 15 March 2003 shortly after a suicide bombing on Haifa bus (by Mamoud al-Qawasmeh on March 5, 2003) and coordinated suicide shooting attacks on Israeli settlements by others on the team (March 7, 2003, Muhsein, Hazem al-Qawasmeh, Fadi Fahuri, Sufian Hariz) and before another set of suicide bombings by team members in Hebron and Jerusalem on May 17–18, 2003 (Fuad al-Qawasmeh, Basem Takruri, Mujahed al-Ja'abri). Although Hamas claimed responsibility for the Dimona attack, the politburo leadership in Damascus and Beirut was clearly initially unaware of who initiated and carried out the attack. It appears that Ahmad al-Ja'abri, military commander of Hamas's Izz ad-Din al-Qassam Brigades in Gaza requested the suicide attack through Ayoub Qawasmeh, Hamas's military liaison in Hebron, who knew where to look for eager young men who had self-radicalized together and had already mentally prepared themselves for martyrdom.[287][288]

The Islamic State in Iraq and the Levant utilizes suicide attacks against government targets before they attack. The attackers can use a wide range of methods, from suicide vests and belts to bomb trucks and cars and APCs filled to the brim with explosives. Usually, the suicide bomber involved in a "martyrdom operation" will record his last words in a martyrdom video before they start their attack and will be released after the suicide attack was done.

A study published by The Guardian in 2017 analyzed 923 attacks done between December 2015 and November 2016 and compared the military tactic to those used by kamikaze operations.[291] Charlie Winter, author of the study, indicated that ISIL had "industrialized the concept of matyrdom". Most (84%) of suicide attacks were directed towards military targets usually with armed vehicles. About 80% of the attackers were of Iraqi or Syrian origin.[291]

Suicide bombings are often followed by heightened security measures and reprisals by their targets. Because a successful suicide bomber cannot be targeted, the response is often a targeting of those believed to have sent the bomber. Because future attacks cannot be deterred by the threat of retaliation if the attackers were already willing to kill themselves, pressure is great to employ intensive surveillance of virtually any potential perpetrator, "to look for them almost everywhere, even if no evidence existed that `they` were `there` at all".[292]

In the West Bank the IDF has at times demolished homes that belong to families whose children (or landlords whose tenants) had volunteered for such missions (whether successfully or not).[293][294]
Other military measures that were taken during the suicide attack campaign included: A widescale re-occupation of the West Bank and blockading of Palestinian towns; "targeted assassinations" of militants, (an approach used since the 1970s); raids against militants suspected of plotting attacks, mass arrests, curfews, and stringent travel restrictions; and physical separation from Palestinians via the 650-km (400-mile) "security barrier" in and around the West Bank.[295][296] cide bombing campaign in 2003–04 involThe Second Intifada and its suicide attacks are often dated as ending around the time of an unofficial ceasefire by some of the most powerful Palestinian militant groups in 2005.[295] A new "knife intifada" started in September 2015, but although many Palestinians were killed in the process of stabbing or attempting to stab Israelis, their deaths were not "a precondition for the success" of their mission and so are not considered suicide attacks by many observers.)[17]

In the United States, the element of suicide in the major attack on it (the 9/11 attacks) persuaded many that previously unthinkable, "out of the box" strategic policies in a "war on terrorism" — from "preventive war" against countries not immediately attacking the US, to almost unlimited surveillance of virtually any person in the United States by the government without normal congressional and judicial oversight — was necessary.[292] These responses "produced their own costs and risks — in lives, national debt, and America's standing in the world".[292]

The "heightened security measures" also affected the target populations. During the bombing campaign Israelis were questioned by armed guards and given a quick pat down before being let into cafes.[177] In the US, the post-9/11 era meant "previously inconceivable security measures—in airports and other transportation hubs, hotels and office buildings, sports stadiums and concert halls".[177]

Results

Early Israeli construction of West Bank barrier in 2003

One of the first bombing campaigns utilizing primarily suicide attacks had considerable success. In the early 1980s Hezbollah used these bombing attacks targeting first foreign peacekeepers and then Israel. The result in both cases was withdrawal from Lebanon by the targets.[297]

Other groups have had mixed results. The Liberation Tigers of Tamil Eelam (LTTE) pioneered the use of suicide bombings against civilian and political targets and in 2000 were called (by Yoram Schweitzer) "unequivocally the most effective and brutal terrorist organization ever to utilize suicide terrorism".[17] Their struggle for an independent state in the North and East of the island lasted for 26 years and led to the deaths of two heads of state or government, several ministers, and up to 100,000 combatants and civilians (by a UN estimate).[298] Politically its attacks succeeded in halting the deployment of the Indian peace keeping troops to Sri-Lanka and the subsequent postponement of the peace-talks in Sri-Lanka.[17] Nonetheless it ended in May 2009 not with an independent "Eelam", but with the overrunning of LTTE strongholds and the killing of its leadership by the Sri Lankan military and security forces.

It is more difficult to determine whether Palestinian suicide bombings have proved to be a successful tactic. Hamas "came to prominence" after the first intifada as "the main Palestinian opponent of the Oslo Accords" ("the US-sponsored peace process that oversaw the gradual and partial removal of Israel's occupation in return for Palestinian guarantees to protect Israeli security")[299] according to the BBC.[299][300]
The accords were sidetracked after the election in 1996 of right wing Israeli leader Benjamin Netanyahu. Hamas's suicide bombings of Israeli targets (from 1994–1997 there were 14 suicide attacks killing 159—not all of which were attributed to Hamas)[301] "were widely" credited for the popularity among Israelis of the hardline Netanyahuof,[299] who — like HAMAS — was a staunch opponent of the Oslo accords, but an even stauncher enemy of HAMAS).

The efficacy of suicide bombing however, does not appear to have demonstrated by the al-Aqsa Intifada. During this Intifada, the number of suicide attacks increased markedly,[302] but petered out around 2005 following harsh Israeli security measures (mentioned above) such as "targeted assassinations" of Palestinians reportedly involved in terrorism, and the building of a "separation barrier" that severely hampered Palestinian travel, but with no withdrawal by the Israelis from any occupied territory.

The drop in suicide bombings in Israel has been explained by the many security measures taken by the Israeli government,[174][295] especially the building of the "separation barrier",[303][304][305] and a general consensus among Palestinians that the bombings were a "losing strategy".[305] The suicide (and non-suicide) attacks on civilians had "a major impact" on the attitudes of the Israeli public/voters,[306] creating not demoralization, but even greater support for the right-wing Likud party, bringing to office another hardliner, former general, prime ministerAriel Sharon. In 2001, 89% of Israeli Jews supported the Sharon government's policy of "targeted assassinations" of Palestinian militants involved in terrorism against Israel, the number rising to 92% in 2003.[306] Opinion polls of the Jewish Israelis found 78–84% support for the "separation barrier" in 2004.[307]

In the case of the 9/11 attacks in the US, at least in the short term, the results were negative for Al-Qaeda, as well as the Taliban Movement. Since the attacks, Western nations have diverted massive resources towards stopping similar actions, as well as tightening up borders, and military actions against various countries believed to have been involved with terrorism.[308] Critics of the War on Terrorism suggest the results were negative, as the proceeding actions of the United States and other countries has increased the number of recruits, and their willingness to carry out suicide bombings.

Suicide bombings are those that involve the deliberate death of the perpetrator. We’re not just talking about a reckless charge in battle. The focus is on those attacks where the perpetrator functions as a sophisticated guidance system for the weapon. They function as part human and part weapon. In this way they are suicide attacks rather than suicidal attacks.

Palestinian terrorism during the second Intifada clearly affected the political preferences of the Israeli electorate. Sharon's resounding victory in the 2001 election was one indication of this effect. Another was the Likud party's decisive win in the 2003 Knesset elections, doubling the number of its seats in parliament (from 19 to 38), while the rival pro-negotiation center-left Labor party lost seven seats (dropping from 26 to 19 seats). Not only did Palestinian terrorism boost the electoral appeal of the political right in Israel, it also helped to bring about a rightward shift in the political positions of the Israeli public. In general, more Israelis identified themselves as right-wing and fewer as left-wing. ...

In 2001, for instance, 89 percent of Israeli Jews supported the Sharon government's policy of "targeted assassinations" of Palestinian militants involved in terrorism against Israel
